<div dir="auto">Hi Patrick, I would agree that using the fused connection on the "ignition switched" side of the fuse block as the source would be a good idea. The ignition switch is not fuse protected so by using that as a source you do run a risk of "letting the smoke out" should a short to ground occur in your fan system. <div dir="auto">You may find that the electrical demands of your fan are more than the fuses can handle as the system was not designed with heavy continuous loads in mind. </div><div dir="auto">To circumvent that issue you could use the unfused side of the "<span style="font-family:sans-serif">ignition switched" section of the fuse block as the source and install an "in line" fuse to protect the fan circuit. </span></div><div dir="auto"><span style="font-family:sans-serif">I cannot overemphasize the importance of protecting the fan circuit with a fuse, it very easy to damage a wiring harness and replacing one is a major undertaking. </span></div><div dir="auto"><span style="font-family:sans-serif"><br></span></div><div dir="auto"><span style="font-family:sans-serif">M</span></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, May 25, 2019, 3:17 AM Patrick & Caroline Quinn, <<a href="mailto:p_cquinn@tpg.com.au" target="_blank" rel="noreferrer">p_cquinn@tpg.com.au</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="EN-AU" link="blue" vlink="purple"><div class="m_8615921404074116746m_522225868468857056WordSection1"><p class="MsoNormal"><span style="font-family:"Times New Roman","serif"">Hello<u></u><u></u></span></p><p class="MsoNormal"><span style="font-family:"Times New Roman","serif""><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-family:"Times New Roman","serif"">Seeking advice from those who understand automotive electrics.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-family:"Times New Roman","serif""><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-family:"Times New Roman","serif"">My real Healey has an electric fan in front of the radiator that was controlled by a thermo switch.
